Do you get an error message?
I'm guessing that you tried the Insert > All Report Tiles menu.
Note that you need to have some rows in the response table to see the tiles.
Turns out I had to:
Clear all filters
Get out of Private View
Insert > All Report Tiles was no longer greyed out
After I clicked Insert > All Report Tiles it took a minute or so before they all reappearred.
They came back out of order.
Not in the order of the form or the order on the View Responses area.
